Summary for version 7.4a

Version 7.4a is an interim release extending the capabilities of the original version 7.4 release. A number of bugs have been fixed in this release. In addition some enhancements are available.

General

• Support for Intel Fortran compiler on PC Windows platform (in addition to Compaq Fortran).
• New "overwrite" command line option.
• Routines that calculate the position of out-of-plane crack face nodes have been made more reliable for cases where the out-of-plane growth is significant.
• Element sets for split set elements are now separated into one element set for each side of the split rather than a single element set for the entire split set.
• A warning is issued when the license file is close to expiry.
• A new crack-block, st12x1, is available.

Abaqus interface

• Resolution of the interfacing issues introduced by changes in Abaqus 6.5-4. At the time of release Zencrack 7.4a was tested with Abaqus versions up to and including 6.6-1.
• Stress intensity factors are now calculated from displacements taking into account large displacements in an analysis with NLGEOM=YES.
• K factor and T-stress output can be requested for all VCE sets rather than just for the "straight ahead" VCE set.
• A restart option is added to allow re-run and continuation of analyses.
